FITMENT NOTES
All applications and dial descriptions supplied by the merchant; exact factory pairings not independently verified. Confirm end-link curvature, actual 20mm lug spacing, spring-bar specification, hole position, case clearance and secure seating on the exact watch. A shared 20mm width or 40–41mm case size does not establish cross-family compatibility. Check each Portugieser family independently and verify Portofino fit before representing it as compatible. Professional fitting recommended.
EXCLUSIONS & INGENIEUR NOTICE
Ingenieur Automatic 1955 IW3233 is not represented as compatible. The supplied 22mm / 21.5mm lug-width alternatives have not been verified; measure the exact case rather than assuming either figure.
Integrated Ingenieur IW3289 attachments and other proprietary connectors.
Any other lug width, incompatible curved end-link geometry, spring-bar arrangement or insufficient clearance.
SIZE & IDENTIFIER NOTES
Approx. 175–180mm uninstalled, as supplied; no guaranteed 8.25-inch or larger wrist fit. IW3716 / IW3583 / IW3565 and the listed full references identify watch applications, not a verified bracelet MPN. Watch not included.

Material

Genuine OEM components - reference-verified and individually inspected before dispatch. Materials and finish meet the original manufacturer's specification.

Clasp & Hardware

OEM clasps are machined from 316L polished steel with twin-trigger deployant mechanisms. Featuring the exact same hardware finish as the factory component.

OEM Original
316L polished clasp — twin-trigger
Generic Aftermarket
Standard pin buckle or low-grade clasp

Authentication

Every OEM strap is reference-verified and matched to the manufacturer part number. It arrives with traceable provenance and a certificate of authenticity.
